WASTE-VALVE.

Specification of Letters Patent.

Patented Jan. 20,191.11.

To all whom it may concern Be it known that I, FRANCIS J. Tome-mon, residing at Pittsburgh, in the county of Allegheny and State ot Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in vWaste-Valves, of which improvement the following is a specification.

My invention has to do with valves or controls for the waste outlets ot sanitary structures such as basins, bath-tubs, and like receptacles, and has particularly to do with waste-controls consisting of a casing, having a valve seat at one end thereof, and a stem movable vertically through a tubular eXtension of said casing, the stem being provided at its lower end with a closure for the valve seat. As usually constructed, the inner wall of the tubular extension of such casings 'is provided with a spiral groove, and the stem carries at its upper end a lug adapted to tit into such groove, whereby a turning of the stem raises it, together with the valve closure a predetermined amount. And in order to guide such closure to its seated position, a sleeve usually extends below the closure and into the discharge pipe. iVaste controls, as thus constructed, have several disadvantages which it is the object of my invention to overcome. In the iirst place, the amount of vertical movement of the stem, when turned to open the valve, is limited, and as a result thereof there is usually a gurgling noise caused by the waste water flowing through the perforate tubular extension oi the valve closure; and secondly, the groove formed on the interior of the casing, besides being expensive to manufacture, affords a place oit lodgment for such impurities as may be in the waste-water, and also renders relatively inaccessible for cleaning purposes the portion of the casing below it.

It is the object of my invention therefore to provide an inexpensive valve of the character described, which may be easily operated without noise, and which may be kept in a clean sanitary condition.

In the accompanying drawing, which forms part of my specification, I have illustrated in vertical sectional view a waste control embodying my invention.

The casing of the waste control, shown in the drawing, consists of a tube or pipe 1 and a T pipe-connection 2, secured to said pipe by means of an adjustable slip joint 3.

The bottom portion ot' said T-member is provided with a valve seat 4t, and connected tothe lower orifice and sido orifice ot said member are pipes 5 and (5 leading, respectively, to a discharge pipe and trom a basin, tub or like receptacle. The top of the tube l is shown extending through the rim 't' of the receptacle to be drained and secured thereto by means ot' suitable clamping nuts 8, 9. The stem 10, provided with a valve closure 1l at its lower end and with a suitable handle 12 at its upper end, extends through the tube 1.

In order to hold the stein in raised 01' open-val ve position, I provide a yielding means for engaging such stem and the casing through which it extends, and for holding the stem in elevated position. The means, which I have particularly shown in the drawing for such end, are preferably spring arms 13 secured to the stem 10 and adapted to bear yieldingly against the inner wall of the tube 1. By using a plurality of such arms 13 the stem 10 may be held by them in central position within the tube 1 and hence the usual sleeve 14- (shown in dotted .lines in the drawings) need not be used for guiding the valve closure 11 into its closed position. It will be seen that, by the use of such stem-supporting and at the same time stem-positioning means, the inner wall of the tube 10 may be smooth throughout and therefore readily accessible for cleaning. Also, the flow of the waste water from the pipe (S to the pipe 5 will be noiseless, because such flow will not be interrupted by the usual depending sleeve 1411 which has been a necessary part oi similar waste valves as heretofore constructed.

I claim as my invention:

1. A waste control for sanitary installations, comprising a tubular casing having a valve seat thereon, a stem movable through said casing and provided with a closure for said valve seat, and a plu'ality of spring arms secured to one and bearing yieldingly on the other ot said members, said arms being e'tl'ective in and ot themselves to support said stem at variable open valve positions and to guide said valve closure to said seat.

2. A waste control for sanitary installations, comprising a tubular casing having a valve seat at its lower end, a stem n'iovable through said casing and provided at its lower end with a closure tor said valve seat, and a plurality of spring arms secured to said stem and bearing against the inner Wall of said casing, said arms eiiiective in and of themselves to support said stem in openvalve position and to guide said valve elosure to said seat.

3. A Waste control for sanitary installations, comprising an interiorly smooth and uninterrupted easing open at its upper end and having a valve seat at its lower end, a stem movable through said easing and terminating at its lower end with a closure for said valve seat, a plurality of spring arms closure to said seat.

In testimony whereof I have hereunto set my hand;
